Vessel with oxygenation system and decontamination method

ABSTRACT

The waterborne vessel, in one embodiment, utilizes an underwater tunnel through which passes flowing water, an ozone gas generator, an ozone plus hydroxyl radical gas generator and a source of atmospheric oxygen. A manifold mixer mixes pressurized water independently with the ozone, the ozone plus hydroxyl radical gas and the atmospheric oxygen to produce corresponding oxygenated water mixtures. Each of these oxygenated water mixtures are fed via a conduit system into the confined flow of water passing through the tunnel. A diversion channel with reverse flow channel permits super saturation of diverted flow from the primary underwater tunnel channel to provide super saturated oxygenated water with ozone plus hydroxyl radical gases and atmospheric oxygen water mixtures. A decontamination method is also provided.

This is a regular patent application based upon and claiming priority ofprovisional patent application 60/588,198 filed Jul. 15, 2004.

The present invention relates to a waterborne vessel with an oxygenationsystem which decontaminates surrounding water and a method therefor.

BACKGROUND OF THE INVENTION

Ozone (O₃) is one of the strongest oxidizing agents that is readilyavailable. It is known to eliminate organic waste, reduce odor andreduce total organic carbon in water. Ozone is created in a number ofdifferent ways, including ultraviolet (UV) light, and corona dischargeof electrical current through a stream of air or other gazes oxygenstream, among others. Ozone is formed when energy is applied to oxygengas (O₂). The bonds that hold oxygen together are broken and threeoxygen molecules are combined to form two ozone molecules. The ozonebreaks down fairly quickly and as it does so it reverts back to pureoxygen, that is, an O₂ molecule. The bonds that hold the oxygen atomstogether are very weak which is why ozone acts as a strong oxidant. Inaddition, it is known that hydroxyl radicals OH also act as apurification gas. Hydroxyl radicals are formed when ozone, ultravioletradiation and moisture are combined. Hydroxyl radicals are more powerfuloxidants than ozone. Both ozone and hydroxyl radical gas break down overa short period of time (about 8-15 minutes) into oxygen. Hydroxylradical gas is a condition in the fluid or gaseous mixture.

Some bodies of water have become saturated with high levels of naturalor man made materials which have a high biological oxygen demand andwhich in turn have created an eutrophic or anaerobic environment. Itwould be beneficial to clean these waters utilizing the various types ofozone and hydroxyl radical gases.

OBJECTS OF THE INVENTION

It is an object of the present invention to provide a waterborne vesselwith an oxygenation system and a method to decontaminate surroundingwater.

It is a further object of the present invention to provide anoxygenation system on a waterborne vessel and a method ofdecontamination wherein ozone and/or hydroxyl radical gas is injected,mixed and super saturated with a flow of water through the waterbornevessel.

It is an additional object of the present invention to provide a supersaturization channel which significantly increases the amount of timethe ozone and/or hydroxyl radical gas mixes in a certain flow volume ofwater thereby oxygenating the water and decontaminating that definedvolume of flowing water prior to further mixing with other water subjectto additional oxygenation in the waterborne vessel.

It is an additional object of the present invention to provide a mixingmanifold to mix the ozone independent with respect to the hydroxylradical gas and independent with respect to atmospheric oxygen andwherein the resulting oxygenated water mixtures are independently fedinto a confined water bound space in the waterborne vessel to oxygenatea volume of water flowing through that confined space.

SUMMARY OF THE INVENTION

The waterborne vessel, in one embodiment, utilizes an underwater tunnelthrough which passes flowing water, an ozone gas generator, an ozoneplus hydroxyl radical gas generator and a source of atmospheric oxygen.A manifold mixer mixes pressurized water independently with the ozone,the ozone plus hydroxyl radical gas and the atmospheric oxygen toproduce corresponding oxygenated water mixtures. Each of theseoxygenated water mixtures are fed via a conduit system into the confinedflow of water passing through the tunnel. A diversion channel withreverse flow channel permits super saturation of diverted flow from theprimary underwater tunnel channel to provide super saturated oxygenatedwater with ozone plus hydroxyl radical gases and atmospheric oxygenwater mixtures. A decontamination method is also provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to a waterborne vessel with an oxygenationsystem and a method to decontaminate water surround the vessel.

FIG. 1 diagrammatically illustrates waterborne vessel 10 having anoxygenation system 12 disposed in an underwater tunnel 14 beneath thewaterline of vessel 10. In general, water flow is established throughtunnel 14 based upon the opened/closed position of gills 16 and theoperation of the propeller at propeller region 18. Tunnel 14 issometimes called a decontamination tunnel. the tunnel may be a chamberwhich holds the water to be decontaminated a certain period of time suchthat the gasses interact with the water to oxidize the criticalcompounds in the water. Water flow through tunnel 14 is oxygenated andcleaned. Rudder 20 controls the direction of vessel 10 and deflectorblade or vane 22 controls the direction of the output flow of oxygenatedwater either directly astern of the vessel or directly downwards intolower depths of the body of water as generally shown in FIG. 9. The flowpath varies from full astern to full down. Lifting mechanism 24 operatesto lift deflector blade 22 from the lowered position shown in FIG. 1 toa raised position shown in FIG. 8A. Blade 22 can be placed in variousdown draft positions to alter the ejected flow of the oxygenated,partially treated water from the body of water surrounding vessel 10.

The crew may occupy cabin 26. A trash canister 28 receives trash fromtrash bucket 30. Trash bucket 30 is raised and lowered along verticalguide 32. Similar numerals designate similar items throughout thedrawings.

FIG. 2 diagrammatically shows a side elevational view of vessel 10without the trash bucket and without cabin 26. It should be noted thatthe waterborne vessel need not include trash container 28 and trashgathering bucket 30. The vessel includes oxygenation system 14 whichoxygenates a flow of water through underwater tunnel 14.

FIG. 3 diagrammatically illustrates a top schematic view of vessel 10.Bow 34 has laterally extending bow wings 36, 38 that permit a flow ofwater into an upper deck region. Trash bucket 30 is lowered into thisflow of water on the upper deck to capture floating debris and trashfrom the water being cleaned by the vessel 10. The trash bucket 30(FIG. 1) is then raised and the contents of bucket 30 is poured overinto trash container 28. The extended position of bow wings 36, 38 isshown in dashed lines.

FIG. 4A shows one embodiment of the oxygenation system. A source ofoxygen 40, commonly atmospheric oxygen gas, is supplied to a gasmanifold 42. In addition, oxygen gas (atmospheric oxygen gas) issupplied to extractor 43 (manufactured by Pacific Ozone) which createspure oxygen and the pure oxygen is fed to a corona discharge ozonegenerator 44. The corona discharge ozone generator 44 generates pureozone gas which gas is applied to gas manifold 42. Ozone plus hydroxylradical gases are created by a generator 46 which includes a UV lightdevice that generates both ozone and hydroxyl radical gases. Oxygen andsome gaseous water (such as present in atmospheric oxygen) is fed intogenerator 46 to create the ozone plus hydroxyl radical gases. The ozoneplus hydroxyl radical gases are applied to gas manifold 42. Atmosphericoxygen from source 40 is also applied to gas manifold 42. Althoughsource oxygen 40 could be bottled oxygen and not atmospheric oxygen(thereby eliminating extractor 43), the utilization of bottled oxygenincreases the cost of operation of oxygenation system 12. Also, the gasfed to generator 46 must contain some water to create the hydroxylradical gas. A pressure water pump 48 is driven by a motor M and issupplied with a source of water. Pressurized water is supplied toair/gas manifold 50. Water/gas manifold 50 independently mixes ozone andpressurized water as compared with ozone plus hydroxyl radical gas pluspressurized water as compared with atmospheric oxygen plus pressurizedwater. In the preferred embodiment, water is fed through a decreasingcross-sectional tube section 52 which increases the velocity of thewater as it passes through narrow construction 54. A venturi valve(shown in FIG. 4B) draws either ozone or ozone plus hydroxyl radical gasor atmospheric oxygen into the restricted flow zone 54. The resultingwater-gas mixtures constitute first, second and third oxygenated watermixtures. The ventri valve pulls the gases from the generators and thesource without requiring pressurization of the gas.

FIG. 4B shows a venturi valve 56 which draws the selected gas into thepressurized flow of water passing through narrow restriction 54.

FIG. 4C shows that oxygenated water carrying ozone can be generatedusing a UV ozone generator 45. Water is supplied to conduit 47, thewater passes around the UV ozone generator and oxygenated water iscreated. This oxygenated water is ultimately fed into thedecontamination tunnel which is decribed more fully in connection withthe manifold system 50 in FIG. 4A.

In FIG. 4A, different conduits, such as conduits 60A, 60B and 60C, forexample, carry ozone mixed with pressurized water (a first oxygenatedwater mixture) and ozone plus hydroxyl radical gas and pressurized water(a second oxygenated water mixture) and atmospheric oxygen gas pluspressurized water (a third oxygenated water mixture), respectively whichmixtures flow through conduits 60A, 60B and 60C into the injector sitein the decontamination tunnel. The output of these conduits, that isconduit output ports 61A, 61B and 61C, are separately disposed bothvertically and laterally apart in an array at intake 62 of tunnel 14(see FIG. 1). Although three oxygenated water mixtures are utilizedherein, singular gas injection ports may be used.

FIG. 12 shows atmospheric oxygen gas from source 40 which is firstpressurized by pump 180 and then fed to extractor 43 to produce pureozone, and ozone plus hydroxyl radical gas UV generator 46 and is fed toconduits carrying just the pressurized oxygen to injector matrix 182.The pure ozone form extractor 43 is fed to an ozone gas generator 44with a corona discharge. these three pressurized gases (pure ozone,ozone plus hydroxyl radical gas and atmospheric oxygen) is fed into amanifold shown as five (5) injector ports for the pure ozone, four (4)injector ports for the ozone plus hydroxyl radical gas and six (6) portsfor the pressurized atmospheric oxygen gas. This injector matrix can bespread out vertically and laterally over the intake of thedecontamination tunnel as shown in connection with FIGS. 4A and 5.

FIG. 5 diagrammatically illustrates a side elevational schematic view ofoxygenation system 12 and, more particularly, tunnel 14 of thewaterborne vessel. A motor 59 drives a propeller in propeller region 18.In a preferred embodiment, when gills 16 are open (see FIG. 6),propeller in region 18 creates a flow of water through tunnel 14 ofoxygenation system 12. A plurality of conduits 60 each independentlycarry either an oxygenated water mixture with ozone or an oxygenatedwater mixture with ozone plus hydroxy radical gases or an oxygenatedwater mixture with atmospheric oxygen. These conduits are vertically andlaterally disposed with outputs in an array at the intake 64 of thetunnel 14. A plurality of baffles, one of which is baffle 66, isdisposed downstream of the conduit output ports, one of which is outputport 61A of conduit 60A. Tunnel 14 may have a larger number of baffles66 than illustrated herein. The baffles create turbulence which slowswater flow through the tunnel and increases the cleansing of the waterin the tunnel with the injected oxygenated mixtures due to additionaltime in the tunnel and turbulent flow.

FIG. 6 diagrammatically shows a schematic top view of oxygenation system12. The plurality of conduits, one of which is conduit 60A, is disposedlaterally away from other gas/water injection ports at intake 64 oftunnel 14. In order to supersaturate a part of the water flow, adiversion channel 70 is disposed immediately downstream a portion or allof conduits 60 such that a portion of water flow through tunnel intake64 passes into diversion channel 70. Downstream of diversion channel 70is a reverse flow channel 72. The flow is shown in dashed lines throughdiversion channel 70 and reverse flow channel 72. The primary purposesof diversion channel 70 and reverse flow channel 72 are to (a) segregatea portion of water flow through tunnel 14; (b) inject, in a preferredembodiment, ozone plus hydroxyl radical gas as well as atmosphericoxygen into that sub-flow through diversion channel 70; and (c) increasethe time the gas mixes and interacts with that diverted channel flow dueto the extended time that diverted flow passes through diversion channel70 and reverse flow channel 72. These channels form a supersaturationchannel apart from main or primary flow through tunnel 14.

Other flow channels could be created to increase the amount of time thehydroxyl radical gas oxygenated water mixture interacts with thediverted flow. For example, diversion channel 70 may be configured as aspiral or a banded sub-channel about a cylindrical tunnel 14 rather thanconfigured as both a diversion channel 70 and a reverse flow channel 72.A singular diversion channel may be sufficient. The cleansing operationof the decontamination vessel is dependent upon the degree of pollutionin the body of water surrounding the vessel. Hence, the type ofoxygenated water and the amount of time in the tunnel and the legnth ofthe tunnel and the flow or volume flow through the tunnel are allfactors which must be taken into account in designing thedecontamination system herein. In any event, supersaturated water andgas mixture is created at least the diversion channel 70 and then lateron in the reverse flow channel 72. The extra time the entrapped gas iscarried by the limited fluid flow through the diversion channels permitsthe ozone and the hydroxyl radical gas to interact with organiccomponents and other compositions in the entrapped water, cleaning thewater to a greater degree as compared with water flow through centralregion 76 of primary tunnel 14. In the preferred embodiment, two reverseflow channels and two diversion channels are provided on opposite sidesof a generally rectilinear tunnel 14. FIG. 4A shows the rectilineardimension of tunnel 14. Other shapes and lengths and sizes of diversionchannels may be used.

When the oxygenation system is ON, gills 16 are placed in their outboardposition thereby extending the length of tunnel 14 through an additionalelongated portion of vessel 10. See FIG. 1. Propeller in region 18provides a propulsion system for water in tunnel 14 as well as apropulsion system for vessel 10. Other types of propulsion systems forvessel 10 and the water through tunnel 14 may be provided. The importantpoint is that water flows through tunnel 14 and, in a preferredembodiment, first, second and third oxygenated water mixtures(ozone+pressurized water; ozone+hydroxyl radical gas+pressurized water;and atmospheric oxygen+pressurized water) is injected into an inputregion 64 of a tunnel which is disposed beneath the waterline of thevessel.

In the preferred embodiment, when gills 16 are closed or are disposedinboard such that the stern most edge of the gills rest on stop 80,vessel 10 can be propelled by water flow entering the propeller area 18from gill openings 80A, 80B. When the gills are closed, the oxygenationsystem is OFF.

FIG. 7 diagrammatically illustrates the placement of various conduits inthe injector matrix. The conduits are specially numbered or mapped as1-21 in FIG. 7. The following Oxygenation Manifold Chart shows what typeof oxygenated water mixture which is fed into each of the speciallynumbered conduits and injected into the intake 64 of tunnel 14.Oxygenation Manifold Chart Gas Tubes O₃ + OH 1, 8, 16; 7, 15, 17 O₃ 3,4, 5, 11, 12, 13 O₂ 2, 9, 10, 18, 20; 6, 14, 19, 21

As noted above, generally an ozone plus hydroxyl radical gas oxygenatedwater mixture is fed at the forward-most points of diversion channel 70through conduits 7, 15, 17, 1, 8 and 16. Pure oxygen (in the workingembodiment, atmospheric oxygen) oxygenated water mixture is fedgenerally downstream of the hydroxyl radical gas injectors at conduits19, 21, 18, 20. Additional atmospheric oxygen oxygenated water mixturesare fed laterally inboard of the hydroxyl radical gas injectors atconduits 6, 14, 2, 9, and 10. In contrast, ozone oxygenated watermixtures are fed at the intake 64 of central tunnel region 76 by conduitoutput ports 5, 4, 3, 13, 12, and 11. Of course, other combinations andorientations of the first, second and third oxygenated water mixturescould be injected into the flowing stream of water to be decontaminated.However, applicant currently believes that the ozone oxygenated watermixtures has an adequate amount of time to mix with the water from thesurrounding body of water in central tunnel region 76 but the hydroxylradical gas from injectors 7, 15, 17, 1, 8, 16 need additional time toclean the water and also need atmospheric oxygen input (output ports 19,21, 8, 20) in order to supersaturate the diverted flow in diversionchannel 70 and reverse flow channel 17. The supersaturated flow fromextended channels 70, 72 is further injected into the mainstream tunnelflow near the tunnel flow intake.

Further additional mechanisms can be provided to directly inject theozone and the ozone plus hydroxyl radical gas and the atmospheric oxygeninto the intake 64 of tunnel 14. Direct gas injection may be possiblealthough water through-put may be reduced. Also, the water may bedirectly oxygenated as shown in FIG. 4C and then injected into thetunnel. The array of gas injectors, the amount of gas (about 5 psi ofthe outlets), the flow volume of water, the water velocity and the sizeof the tunnel (cross-sectional and length) all affect the degree ofoxygenation and decontamination.

Currently, flow through underwater channel 14 is, at a minimum, 1000gallons per minute and, at a maximum, a flow of 1800 gallons per minuteis achievable. Twenty-one oxygenated water mixture output jets aredistributed both vertically (FIGS. 4A and 5) as well as laterally andlongitudinally (FIGS. 6 and 7) about intake 64 of tunnel 14. It isestimated that the hydroxyl radical gas needs about 5-8 minutes ofreaction time in order to change or convert into oxygen. Applicantestimates that approximate 15-25% of water flow is diverted intodiversion channel 70. Applicant estimates that water in the diversionchannel flows through the diverters in approximately 5-7 seconds. Duringoperation when the oxygenation system is operating, the boat can move at2-3 knots. The vessel need not move in order to operate the oxygenationsystem.

FIG. 8 shows an alternative embodiment which is possible but seems to beless efficient. A supply of oxygen 40 is fed into an ozone generator 44with a corona discharge. The output of ozone gas is applied via conduit90 into a chamber 92. Atmospheric oxygen or air 94 is also drawn intochamber 92 and is fed into a plurality of horizontally and verticallydisposed nozzles 96. Manifold 98 consists of a plurality of oxygenationnozzles 96. Manifold 98 can be raised or lowered by any appropriatemeans. In the illustrated embodiment, rotating threaded sleeve 110operates on threaded rod 112 to raise and lower oxygenation manifold 98.Diverter blade 22 can be raised and lowered by another mechanismgenerally shown as lifting mechanism 24 in FIG. 1. Shaft 114 drivespropeller 116 to provide a propulsion system to move water throughtunnel 118. FIG. 8A shows that the water propulsion system to move thewater through the tunnel could be forward the tunnel intake 64 shown inFIG. 6. The alternative embodiment also shows that the tunnel may beforeshortened.

FIG. 8B is a detail showing gas injection nozzle 96 and water flow 120passing through restricted flow channel 122.

FIG. 9 diagrammatically shows that diversion blade 22, when rotateddownward as shown by arrow 142, directs oxygenated and treated wateroutput 144 y the oxygenation systems into lower depths of the body ofwater being treated by vessel 10.

FIG. 10 diagrammatically illustrates aeration injector manifold 98.

FIG. 11 shows aeration injectors 96 having a forward inverted V shapedbody 160 and a rearward generally oval shaped body 162. Air plus ozoneis pumped or drawn into the interior region 164 of V shaped body 160.Water flow is directed through constricted channel 122 and a high degreeof turbulence in region 166 mixes the ozone with the water flow throughconstricted channel 122. This turbulence in restricted flow channel 122causes the ozone and atmospheric oxygen to mix with the water flowthereby oxygenating the water.

FIG. 12 shows a pressurized gas system which has been described earlier.
